Before you're driving for profit, you're driving to cover today's costs. Enter what today costs you and what an average fare's worth, and see exactly where the line is.
Weekly or monthly earnings summaries hide a simple daily reality: the first few fares of any shift aren't profit, they're paying off the hire, fuel, and fixed costs you're already committed to before you even start the engine. Knowing your actual break-even fare count for today — not last month's average — tells you honestly whether an early finish still made the day worthwhile, or whether a slow shift genuinely lost money.
A planning tool, not an accounting record — for your actual tax return, keep a proper log of real income and expenses. See our mileage allowance calculator for that side of things.
